Tag: Diesel Exhaust Fluid

We have been hearing over and over a comment about Diesel Exhaust Fluid that is particularly frightening ,

“Diesel Exhaust fluid is the same as ____ urine”

Fill in the blank with any animal you can think of, we have heard it all but most recently , bat and cow urine. We have also heard of people thinking that urinating in their DEF tank will make the engine run. So the common misconception people have about Diesel Exhaust Fluid is that it is made from urine. This is NOT true, and acting upon this idea could cost you thousands of dollars in repairs to your SCR engine. On this blog, some light will be shed on the subject, and we will finally debunk this myth for good.

Those who believe in this myth used deductive reasoning to get to that conclusion , so according to them:

Urine = Urea

Urea+water= Diesel Exhaust Fluid

therefore Urine+ water= Diesel Exhaust Fluid

WRONG

Urea is an organic chemical compound, or the waste produced by the body after metabolizing protein. But since 1828, German scientist Friedrich Wöhler invented the process to create the synthetic version of urea. In 1870 the process of producing urea through dehydrating ammonium carbamate under conditions of high heat and pressure was invented. So yes, urea can be obtained from urine, but lets find out why Diesel Exhaust Fluid is not just urine and water.

I will be comparing the material data sheets of both automotive grade urea vs human urine.

According to wikipedia, “Human urine is an aqueous solution of greater than 95% water, with the remaining constituents, in order of decreasing concentration urea 9.3 grams/L, chloride 1.87 grams/L, sodium 1.17 grams/L, potassium 0.750 grams/L, creatinine 0.670 grams/L and other dissolved ions, inorganic and organic compounds.” Read the full description here.

The water needed to create Diesel Exhaust Fluid has to be de-ionized and de-mineralized , a process that only a highly specialized filtration machine can achieve.

From all this information we can conclude that even though urine has urea, it is not the correct concentration nor does it have the purity needed. The water that comes from urine is also full of ions and minerals which make it very low quality water.

Diesel Exhaust Fluid is highly concentrated and very pure urea plus de-ionized water .The standards for Diesel Exhaust Fluid are very specific and can be found here.

I hope that this blog has been informative, highlighting the differences between urine and Diesel Exhaust Fluid. Please do not urinate in your DEF tank, the SCR system will be damaged and it will cost thousands of dollars to repair.

Hi folks- we have been on the streets of Houston quiet a bit this past couple of weeks, talking Diesel Exhaust Fluid, right here in our back yard.

What we have found is the continuous confusion about dispensing from closed loop systems. Now, our job here is to help you and our distributor network understand these options; so we felt it was important to reharsh this concept once again.

Our previous post dealt with what you have available as far as distribution channels. One way IBC totes, returnable/refillable, on site refilling, at a glance.

Why don’t we dig in a little deeper on the handling and dispensing of Diesel Exhaust Fluid with a closed loop systems.

What is a DEF closed loop system?Micromatic is the system that we use, it is now company policy that only closed loop systems are being sold with either drums or IBC totes. The pictures below will illustrate the diesel exhaust fluid closed loop system.

Ok, now what we have a better picture of what that system is. The following question came up: What do I need to make this system work for me on one way totes and refilling totes on site?

So, let’s take the first half of the question on one way DEF IBC Totes.

Say you are ready to serve one of your customer with an order of 330 gallons of Diesel Exhaust Fluid in an IBC Tote package. How are you going to create a closed loop system when that tote will eventually be swapped out for a new one?

Starting from the top and working down into the IBC tote, here is what you need: 1) SS coupler, 2) container valve (economical) 3)down tube (275 gal or 330 gal).

From the SS coupler, you will need to clamp your EPDM hose for your pump. We have these Micromatic parts in stock here in Houston, as well as the diesel exhaust fluid pump dispensers. Call us for more details at 281-377-5845 or email us for equipment information.

1 – Part #756-008B

2- Part# 755-003

3- Part#755-641/1245 g

When the DEF fluid is all used up, you can reuse the coupler on the new IBC coming in already filled with DEF.

The second part of the question deals with servicing your customers by providing on location re-filling. In other words, reuse the same tote by refilling on site. We will discuss this in detail on the next blog entry.
